The First Carbon Nanotube Computer | MIT Technology Review: The carbon nanotube processor is comparable in capabilities to the Intel 4004, that company’s first microprocessor, which was released in 1971...
The nanotube processor is made up of 142 transistors, each of which contains carbon nanotubes that are about 10 to 200 nanometer long...
Theoretical work has... suggested that a carbon nanotube computer would be an order of magnitude more energy efficient than the best silicon computers.

Lightsaber Kinect robotic arm = JediBot | ExtremeTech

Lightsaber Kinect robotic arm = JediBot | ExtremeTech: Basically, the robot arm is pre-programmed with a bunch of “attack moves” and it defends by using the Kinect to track the green lightsaber. To attack, JediBot performs a random attack move, and if it meets resistance — another lightsaber, a skull, some ribs — it recoils and performs another, seemingly random, attack. It can attack once every two to three seconds — so it isn’t exactly punishing, but presumably it would only require a little knob-tweaking to make it a truly killer robot.
